having trouble linking the individual position x, y, z values with the position values from a 3D enabled null
the particle world emitter still works until i move the null in any direction and it just disappears

This should work for x:
p = thisComp.layer("Null 1").transform.position;
d = (p - [thisComp.width/2,thisComp.height/2,0])/thisComp.width;
d[0]
Then just change the last line to d[1] for y and d[2] for z.
You'll probably need to fiddle with the effect's camera paramters to get it to match up exactly.
